Comprehensive Prevention and Control of Stem Rot Caused by Turmeric

Turmeric is an ideal raw material for the extraction of steroid hormone drugs. With the expansion of artificial cultivation area and the increase of time, coupled with abnormal climate, extensive field management, and disease of yellow ginger, the disease has been aggravated year after year. This has often caused the stem base to rot and led to the death of the entire plant, which has become a major obstacle to the production of yellow ginger.

First, the symptoms of turmeric stalk rot mainly damage the rhizome turmeric shoots and stem base. At the beginning of the disease, water-stained spots of different sizes appeared at the base of the stem, gradually expanded, and the leaves became yellow. The lesions around the base of the stem at the late stage of the disease caused the basal tissues to decay gradually. As the transport of moisture nutrients is hindered, the main stems of the aboveground stems die from top to bottom and the leaves become black and wilted. When the humidity is high, the soil is opened and white cotton floe is visible in the diseased area and soil. Great harm.

Second, the transmission of pathogenic bacteria with mycelium latent in the diseased potato and sickness on the winter, or with mycelium and chlamydospore in the soil in winter. Appropriate conditions can cause the disease. It usually begins in May and peaks in June. After harvest, seed potatoes with pathogens can continue to develop and continue to be sown until March of the following year.

Third, the incidence of conditions (a) temperature and humidity. High temperature and high humidity are conducive to the occurrence of root rot of turmeric. The appropriate temperature is 20°C~25°C. The temperature is too low or too high is not conducive to disease. (b) Lighting. Turmeric is a light-tolerant and drought-tolerant plant. Shed cultivation, ventilation, and poor light transmission are susceptible to disease. According to the survey, the incidence of flat-planting and unscratch-planting was 13.15% and 15.61%, respectively, and the incidence of ridge-planting and scaffolding cultivation of sorghum was 5.21% and 3.84%, respectively. (c) Soil. Yellow mud loam and sticky heavy soil are heavy. Should use deep soil, well-drained, loose soil, sandy loam rich in organic matter, soil pH 6 to 7 is appropriate, phosphorus, potash fertilizer can effectively promote the growth of yellow ginger and improve disease resistance. (d) mouthwash. The bacteria can survive in the soil for a long time, and the amount of bacteria accumulated in the replanting plots is relatively heavy.

Fourth, comprehensive prevention and control (a) the selection of pest-free, no rotten seed potato, to prevent the spread of pests and diseases, to ensure that the full Miao Miao. When sowing, use 40% of Fuxing Star EC 8000 times soaking, but also use 50% carbendazim 200 grams per 100 kg seed, 100 kg of water, soak 4 to 5 minutes, dried after sowing. (b) Soil disinfection. In the land where the disease is severe, 70% of thiophanate, 50% of carbendazim, 50% of dextromethorphan or thiram, 1 kg to 1.5 kg of fine soil and 30 kg of fine soil are applied to the soil. The use of lime for disinfection in acid soils can prevent soil-borne diseases. (c) Reasonable rotations. With the grass crops for more than 2 years, turn crops to prevent disasters. (d) Apply sufficient farmyard manure to increase soil organic matter and improve soil. Re-apply phosphorus, potassium fertilizer, clever application of boron, zinc fertilizer, enhance plant resistance to disease. Generally, there are 1500-2000 kg of fertilizer per acre, 50 kg of phosphate fertilizer, 25 kg of potassium fertilizer, or 75-100 kg of special fertilizer for turmeric, mainly based on basal fertilizer. (E) ridge cultivation scaffolding, improve soil aeration, and promote underground stem growth. The ridge is 1 meter wide and the ridge height is 20 centimeters. When the height of the seedling is 30 centimeters, four bamboo raft tower adult frames per square meter are used to promote ventilation, light transmission and moisture flow, promote photosynthesis of leaves, and prevent disease. . (6) Conduct timely chemical control. At the beginning of the disease, 40% of Fuxing Emulsion 8000-fold, 75% of chlorothalonil 1000-fold, 50% of carbendazim, 50% of thiophanate and 86.2% of copper master 500-800 times fluid were used at the site of disease. Irrigating roots, each irrigation 50 ~ 100 ml, irrigation once every 10 days, even irrigation 2 times.

In Ethanol & Alcohol production process, the starches from agricultural products are converted in fermentable sugars with the help of enzymes. Lignocellulosic materials can be used to produce alcohol which is a kind of alternative energy that can replace the limited oil resources. Biomass based ethanol production is mainly composed of 2 steps: cellulose from lignocellulosic biomass is hydrolyzed to produce reduced sugar and reducing sugar is fermented to produce alcohol. Enzymatic hydrolysis of biomass will become the main means of future development because of its low energy consumption, product specificity and conforming to the government's environmental protection policy. Sunson Group supplys Xylanase, Pullulanase, Protease and Amylase for the ethanol & alcohol industry.


Ethanol is made from various agricultural products including corn, cereal and tapioca etc. During ethanol production process, the starches in these agricultural products are converted into fermentable sugars with the help of enzymes. These fermentable sugars are then fermented into ethanol by yeasts. Specifically, the ethanol production process includes four stages: starch liquefaction, starch saccharification, protein and non-starchy polysaccharides hydrolysis, and fermentation.


Benefits:

Promote the growth and reproduction of yeast 
Improve the efficiency of fermentation 
Promote the utilization of raw materials 
Increase the starch conversion rate


This product should be stored in a cool and dry place in sealed container, avoiding insolation, high temperature and damp.  The product has been formulated for optimal stability. Extended storage or adverse conditions such as higher temperature or higher humidity may lead to a higher dosage requirement.


Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
